Number one is the Graupner MC 24 front view.Number two is an inside sot over view with teh back cover removed.Number three shows the module in placeNumber four shows where the modules normally sits and with the module removed you can see teh base with teh five pins sticking out for tne module connection.I guess the easy way would be to hook into th emodule pins, but I would prever to be able to switch between module 36 meg and the FRSky Hack module.

If I am right, I should be able to use a breakout plug and lead set. If I feed off the the plug on the module this could then go to a switch and be changed between the FRSky hack module and the JR Module.

If so I will need to source a plug male and female to suit and a suitable switch, hook up and away we go with a straight plug and play.
